SOIL TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To obtain a soil treatment system capable of reliably and economically carrying out treatment of soil polluted with volatile organic compounds (VOC) such as silt and viscous soil hard to be impregnated with a treatment promoting agent by a simple method. SOLUTION: The soil treatment system is composed of the installation step of installing a loading rod and a recovery rod to an approximately same depth from the upper layer of the polluted soil, wherein the loading rod has a jetting nozzle connected to a treatment promoting agent injection plant for loading a treatment promoting agent to the polluted soil and the recovery rod has a recovery hole connected to a well point treatment agent recovery notch plant for recovering a well point treatment promoting agent; a treatment promoting agent loading and recovering step of loading the treatment promoting agent to the polluted soil by the loading rod after the installation step of the loading rod and the recovery load and at the same time recovering the agent by pumping up water in the same amount as that of the loaded treatment promoting agent through the recovery rod; and purifying the treatment promoting agent-containing groundwater recovered by the recovery rod in the treatment promoting agent loading and recovering step.
